This tangy and sweet Rhubarb BBQ Sauce is a unique twist on classic barbecue—perfect for grilled meats, sandwiches, and more. Easy to make and freezer-friendly!
Combine rhubarb, onion, garlic, and water in a medium saucepan. Bring to a boil, then reduce to a simmer over medium-low heat. Cook uncovered for 10 minutes, or until rhubarb is soft and broken down.
Stir in ketchup, vinegar, brown sugar, honey, Worcestershire sauce, smoked paprika, mustard, salt, and pepper. Simmer for another 10 minutes, stirring occasionally.
Use an immersion blender to puree the sauce directly in the pot until smooth.
Return to the stove and let it simmer for another 5–10 minutes until thickened to your liking. Taste and adjust seasoning as needed.
Let cool, then transfer to a jar or an airtight container. Refrigerate for up to 2 weeks.
